Issue with Codable and JSON - json

Question

I'm trying to avoid use all the boilerplate code stuff without codable.
I apologize if this a dumb question, but why am I getting this error when I'm trying to parse json with codable?
keyNotFound(CodingKeys(stringValue: "name", intValue: nil), Swift.DecodingError.Context(codingPath: [], debugDescription: "No value associated with key CodingKeys(stringValue: \"name\", intValue: nil) (\"name\").", underlyingError: nil))
The json endpoint is structured as follows:
{
"businesses": [
{
"id": "FmGF1B-Rpsjq1f5b56qMwg",
"alias": "molinari-delicatessen-san-francisco",
"name": "Molinari Delicatessen",
"image_url": "https://s3-media3.fl.yelpcdn.com/bphoto/6He-NlZrAv2mDV-yg6jW3g/o.jpg",
"is_closed": false,
"url": "https://www.yelp.com/biz/molinari-delicatessen-san-francisco?adjust_creative=Js10QwuboHe9ZMZF31mwuw&utm_campaign=yelp_api_v3&utm_medium=api_v3_business_search&utm_source=Js10QwuboHe9ZMZF31mwuw",
"review_count": 1058,
"categories": [
{
"alias": "delis",
"title": "Delis"
}
],
"rating": 4.5,
"coordinates": {
"latitude": 37.79838,
"longitude": -122.40782
},
"transactions": [
"pickup",
"delivery"
],
"price": "$$",
"location": {
"address1": "373 Columbus Ave",
"address2": "",
"address3": "",
"city": "San Francisco",
"zip_code": "94133",
"country": "US",
"state": "CA",
"display_address": [
"373 Columbus Ave",
"San Francisco, CA 94133"
]
},
"phone": "[phone]",
"display_phone": "[phone]",
"distance": 1453.998141679007
}
}
I have a struct I created
struct Businesses: Codable {
var name:String
var image_url:String
var is_closed:Bool
var location:[String:String]
var display_phone:String
var url:String
}
Here's how I'm trying to use Codable:
do{
let jsonData = response.data
//created the json decoder
let decoder = JSONDecoder()
//using the array to put values
self.searchResults = [try decoder.decode(Businesses.self, from: jsonData!)]

It's a very common mistake, you are ignoring the root object which – of course – does not have a key name.
And you'll get another error, location is not [String:String]
struct Root : Decodable {
let businesses : [Business]
}
// Name this kind of struct in singular form
struct Business : Decodable {
let name: String
let imageUrl: URL
let isClosed: Bool
let location: Location
let displayPhone: String
let url: URL
}
struct Location : Decodable {
let address1, address2, address3: String
let city, zipCode, country, state: String
let displayAddress: [String]
}
...
let decoder = JSONDecoder()
decoder.keyDecodingStrategy = .convertFromSnakeCase
do {
let jsonData = response.data
let result = try decoder.decode(Root.self, from: jsonData!)
self.searchResults = result.businesses
} catch { print(error) }
